Just wondering if I can put a 90-93 Integra stock rear sway bar on my 91 CR-X Si? Would it fit, and if so, is it bigger?

 

You can use it if you want. Its 1mm larger. Not alot of difference, but if you want to do it will work.

 

Doesn't really sound like its worth investing in. But if you already have it, what the hell.

 

go with an aftermarket one!

 

i have a 91 Integra rear sway on mine. bolts right on using Si mounting hardware (which you obviously already have.) not that much bigger and dosen't make a huuge difference, but i had it laying around in the garage so i said wth.

if you decide to get one, you'll need the Integra bar's mounting bushings.
